I will be in Hong Kong in early March and would like to fly to Huangshan, stay the first night, then go up the mountain and stay for two nights for hiking and photography. I was told a while ago there is a charter flight from Shenzhen to Huangshan 2 times a week? Is this flight still operating? If so, what days of the week and how much does it cost? How to make reservations? I am thinking of taking a train one way and a flight the other way. Any suggestions you might offer aer appreciated.
